Title: Displacement servo gauge
Inventor: REMION MICHEL
IPC: G01F23/44
Filed: 1990-06-12
Abstract: DISPLACEMENT SERVO GAUGE                     Abstract of the Disclosure The  disclosed  level  gauge  is  used  on  a  tank containing  a  liquid.    The  gauges  utilizes  a  displacer suspended on a support wire or tape which is wound on a storage  wheel.    The -storage  wheel  is balanced  by  a counterweight.   Any change in liquid level results in an imbalance which causes a servo motor to energize and rotate the wheel to bring the counterweight and displacer back into balance.  The change in level is determined by counting the steps of motor operation,  The changes in level are determined using the relationship between length and steps of motor operation.  The level gauge is operable to continually correct calculation to compensate for changes in wire length per turn of the spool.

Title: Method and Device for Determining the Output Rate of Virtual Circuits Using a Time Division Transmission Channel
Inventor: THIEBAUT GEORGES
IPC: H04L12/54
Filed: 1990-06-19
Abstract: The invention comprises the use of a memory (MCT) in which to each virtual cell-routing circuit is allocated a location containing a context (CT), defining the conditions for evaluating the bit rate of this virtual circuit and provides, upon the reception of each cell, for the reading of the context of the virtual circuit to which this cell belongs, with a view to evaluating the bit rate of this virtual circuit. The invention further comprises the use of a clock (BC) set aside in order to supply a current time associated with this virtual circuit. 
<??>A start time indicator is recorded in the context (CT) of a virtual circuit and, upon the arrival of a cell of this virtual circuit, the context is read, from the current time, supplied at that moment by the clock, is subtracted the start time supplied by the context read, and the time difference thus established constitutes a measurement of instantaneous bit rate of the virtual circuit, defined as the time interval which has elapsed between two cells, this measurement of instantaneous bit rate being supplied to evaluation means (BT), whereas the current time is then recorded in the context, in the guise of start time.

Title: Corrosion resistant insert
IPC: F24H1/18
Filed: 1990-09-12
Abstract: A corrosion resistant insert of the present invention is used for fitting at an opening in a metallic liquid tank.  The insert has an open end, a radially outwardly extending lip at the open end, a closed end and an axially extending side wall spacing the open end and closed ends from one another.

Abstract: OPTICAL FIBER GUIDE               ABSTRACT OF THE DISCLOSURE         A  moving  optical fiber (10) is guided in its motion  by  an  annular  guide  apparatus  (40) which receives  the optical fiber (10) within an inner bore (66)  and  stabilizes  its  transverse position as it moves   longitudinally.      The  guide  (40)  has  a plurality  of  gas jets extending into the inner bore (66)  that  create  a  cushion of gas to maintain the position  of  the optical fiber (10) in the center of the  bore  (66),  without the  need for any physical contact  between  the bore (66) and the optical fiber (10).    The  annular guide (40) is preferably formed from  a  housing  (42) that defines a gas plenum (74) and  a  flow  control  plate  (52)  that  fits to the housing   (42)   and  has  circumferentially  spaced, radially  extending  gas  flow  passages  (54) etched therein.   A gas flow introduced into the plenum (74) from  an  external  source  is distributed to the gas flow  passages (54) and thence to the inner bore (66) to  prevent  the  optical  fiber (10) from physically contacting the guide (40).

Title: Apparatus for utilizing water as an energy source
Inventor: SCHELLHORN KARL-HEINZ
IPC: F03B17/06
Filed: 1990-12-06
Abstract: ABSTRACT      An apparatus for using water as an energy source.  The apparatus has at least one hollow body which operates in an upward and downward vertical direction under the influence of water from a first upper reservoir.  This water fills the hollow body to move it downwardly into a second lower water reservoir on which it had been floating.  When a valve at the bottom end of the elongated hollow body is opened, the body quickly moves upwardly to its floating position.  The upward and downward movement of the hollow body is converted into rotational movement of an output shaft.  The output shaft rotates in one direction at all times in response to both the upward and downward movement of the hollow body.  The entire apparatus is arranged in a unitary modular form so that the modules can be stacked to increase the desired power output.

Patent CA-2040002-A1 (CA)
Inventor: MC CLUNG DUANE G
IPC: A47B95/04
Filed: 1991-04-08
Abstract: This relates to a panel of the type which includes a core covered by veneer and generally relates to a furniture panel. Such panels have a front edge which is contoured and is generally rounded. The panel in question has a generally rounded edge which terminates at the bottom thereof in a low radius portion, i.e., on the order of 2 mm. Because of this very low radius it is virtually impossible to take a single sheet of veneer and wrap it around such a radius. The problem is solved by using two separate veneers, an upper and a lower, and where the low radius edge portion is, machining a channel in the core and filling the channel with a projecting plug which then has the projecting portion thereof machined to provide a smooth continuous surface. Additionally, in order that there may be no demarcation of materials, the plug is formed of the same material as the veneers.

Title: Multi-hull boat
Inventor: TOLLET DANIEL
IPC: B63B1/10
Filed: 1991-05-06
Abstract: A multi-hulled boat has at least three hulls, with the outside hulls extending forward beyond the central or inside hull or hulls.  The hulls are tapered with a cross-sectional configuration that increases in size front to rear, thus forming a channel or tunnel between adjacent hulls which decreases in cross-sectional size front to rear.  Air entering the tunnels is compressed, thus imparting a lifting force to the hulls lifting the hulls partially out of the water to decrease the hydraulic drag on the hulls.  The hulls have identical cross-sectional areas at identical transverse planar sections thereof.  The bottom of each hull is flat and inclined at an angle with the horizontal.  The hull bottoms join the hull sides at a chamfer which increases in size front to rear.  Shutters or flaps may be used to partially or fully close off the tunnels between the hulls to control airflow or to trap water-borne material to be collected and recycled.

Filed: 1991-04-30
Abstract: Abstract of the Disclosure A conditioning implement having first and second conditioning rolls, one of which is movably mounted, includes a mounting system for selectively urging the movable roll toward the other roll. The mounting system includes a pair of mounting plates adapted for placement one on either side of the movable roll, with the mounting plates being pivotably mounted to a frame.  An adjustment subassembly is connected to the mounting plates.  In a first position, the adjustment subassembly exerts a maximum biasing force on the mounting plates for urging the movable roll toward the other roll with a maximum biasing force.  In a second position, the adjustment subassembly relieves the biasing force exerted on the mounting plates, thus allowing movement of the movable roll away from the other roll to accommodate passage of a mass of material therethrough.  A system is provided for interconnecting the adjustment subassembly with a lifting and lowering system for the conditioner.
